PUZZLE.

SPECIFICATION forming part of Letters Patent No. 700,573, dated May 20, 1902.

Application filed August 23, 1901. Serial No- 73,044- (No model.)

To atZZ whom it may concern.-

Be it known that I, WALTER B. SMITH, residingin Marlboro, county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in Puzzles; and I do hereby declare the following to be a full and clear description thereof. I

My invention relates to puzzles and educational appliances.

The object of the present invention is to provide a series of blocks or tablets having a series of designated characters thereon, such as numerals, which may be arranged in' such order that upon being added a given sum or result may be deduced.

For this purpose my invention consists in the following construction and combination of parts, which will first be fully described in detail and the patentable novelty therein then set forth and claimed.

In the drawings, Figure 1 represents a perspective View of a device embodying my invention. Fig. 2 is a transverse section of the same.

1 represents a box or container adapted to hold a stated number of cubes, blocks, or tablets. The box 1 is preferably of rectangular shape. The series of blocks 2 are preferably of square form upon their faces and may be of any thickness desired. The block 3 is preferably oblong and twice the area of the blocks 2.

In a preferredform I employ ten blocks 2, having the numerals 0, 1, 2, 3, (4,7 g 5,7) (6,77 i 7,77 (8,77 (9.77

blocks are adapted to be inserted in the box at random. The block 3 has the. number 100 thereon. The educational feature involved in the appliance is to rearrange the series of blocks 2 within box 1 in double columns, so that when added by two additions printed in suitable color thereon.

A cheap and efficient method of carrying out my invention is to make the blocks of stained wood, with the characters or figures Where only a single face of the series of blocks 2 and 3 are used, the characters or figures are printed on the top surface only.

The solution of the puzzle is obtained bydisposing the blocks 5, 6, and 7 at the top of the box in any order in the right-hand column and the figures 1, 3, and 4 in any order at the top of the box in the lefthand column. Below the blocks so arranged, for example, thus are-placed the blocks 9 and 8 in the order given, so that the sum and result are p the 98 being the total of 17, 35, and 46. There remain but two additional blocks 0 and 2, which, being added'to 98, give 100 which is the solution of the problem. The

In a puzzle, a box containing ten blocks, one for each numeral, adapted to count one hundred in two additions, blocks 1, 3, 4, 5, 6, 7 In testimony whereof I have affixed my sigbeing so disposed in two columns that when nature in the presence of two witnesses. added their total will be equal to the blocks 9, 8, in the order stated, and the blocks 0, 2,

5 in the order stated, disposed beneath the Witnesses: U

blocks 9, 8, whereby the sum total of 100 is JOHN DALTON, obtained. 4 EDGAR WEEKS.
